feature request: sponsor json endpoint

[kylerisse]

Can you please create a sponsor endpoint similar to what we're doing for the schedule? JSON preferred. This would allow us to dynamically use the same content that exists at https://www.socallinuxexpo.org/scale/23x/sponsors for use with the digital signs. Ideally this would include:

• name
• image url
• list of tiers (ie: diamond, gold, media, etc, etc)

I'll work with whatever format is easiest to maintain for you. Please let me know if you have any questions or concerns.
